Variation in Cold Resistance and Growth in Eucalyptus viminalis
To isolate frost-hardy, fast-growing provenances of E. viminalis for the Southeastern United States, 98 seed lots were tested by International Paper Company during 1972-80. Annual rainfall and its seasonal distribution were not believed to be limiting factors in growing eucalypts in this region. However, freezing temperatures and their duration and fluctuations caused significant damage to many of the provenances. The degree of damage varied greatly among the provenances with the most frost-hardy sources not necessarily the best growers. Some individual trees performed well in both characteristics. Due to high variation in frost hardiness and growth, the actual yield of E. viminalis is much below the potential yield in the Southeast. Commerical reforestation using this species is not recommended unless more frost-hardy strains are developed through a genetic improvement program.
